6pcs Car Fuel Injection System Fuel Injector nozzle 0280157012 For TT 2004 2005 2006; Automobile fuel injectors need to be kept clean frequently to prevent clogging and uneven fuel injection； Replacing the fuel injector can improve the combustion process, reduce the production of incompletely burned fuel residues and harmful gases, and reduce the emission level of the car； High temperature resistant structure can adapt to engine high temperature environment without deformation. Stable fuel injection volume reduces engine jitter, idle instability and weak acceleration., Manufacturer: KVGAEANDNK
